ChaosDMX is an open-source DIY DMX512 interface on an ESP32-S2 (Lolin S2 Mini). It is meant to bridge lighting-control software (e.g. QLC+) to stage equipment — fixtures, moving heads, fog machines — over WiFi. The firmware serves the web UI, stores the settings in NVS and joins your network in access-point or station mode; no companion app or cloud service is involved.
